WILLIAM E. HAWKINS, JR, OF PELHAM, NEW YORK.

Application filed June 7,

T all whom it may concern:

Be it known that I, W ILLIAM It. HA\VKL\'F,

.Jr., a citizen of the. United States, and a others, may be attained, is illustrated in the.'

accompanying drawings, in which-- Figure 1 is a side view of my improved wrench showing the jaws in position to grasp an object.

Figure 2 is asimilar view but showing the jaws in open position. i

Figurc.3'is a perspective view of the wrench.

In the'accompanying drawings the numeral 5 indicates a shank having a fined jaw Q icidly secured thereto at oneend and in a manner common to wrenches of this parts in fact comprising a fixed jaw with a sup orting extension therefrom. The in-' 19.1 e ge of the shank is formed with serraengage mom 8 beginnin n-short distance from the jaw 6 and exten the handle 7, the j ing a holder edge on said shank. The morable jaw9 is supported by and at the end of a lever .h'andle'ltl, this 'aw 9 being so disposed that when said lever handle is in its closed position, as shown in Figure 1, the working face of the jaw 9 will be substantially parallel with the working face of the fixed jaw 6, A detent 11 projects from the backof the lever handle in proximity to the jaw 9, this detent being arranged to the teeth, or serrations 8'to retain the jaw 9 in fix positions with respect to the jaw 6 As a means for supportin the jaw 9 and the lever handle 10 I provi e a aw carrier 12 of 'U-shup and that is forum to extend around the outer ed and on opposite sides of the shank 5 an handle 7, this carrier being open on what may be termed its front Specification of Letters Patent.

edge, and within this opening the jaw 9 is pivotully securedas by mealns of a. pivot 13 extending through the side parts of the carrier. i

The fixed jaw and its attached handle and shank and the movable jaw with its lever handle are-both punched or cut from metal in a manner that will be-readil understood, and for which reason the fixe and ivoted jaw members together with their han les are preferably formed from metal of the same thickness, this formation of said members of uniform thickness also simplifying the formation of the jaw carrier 12 in that it is necessary only to bend it at the back, and,

if desired, it ma be cut away as shown in the drawings. he ends of these handles may be formed into screw drivers of diffcrent sizes, and as illustrated in the drawln r Fhe detent 11 may be formed in any suitable manner, a. satisfaoto construction embodyin that in which t e detent is separately armed and thereafter attached to the jaw as shown in the drawin When thus constructed this detent may be hardened thereby enabling it to withstand the wear incident to its use.

The construction is such that the jaw members may be constructed at a. minimum cost; the formation of the carrier is extremely simple and inexpensive; and the assembling of the device 1s so simple as to require little consideration as to expense of manufacture.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention,'to ther with the device which I now. consi or to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means.

1. AL wrench comprising a fixed jaw member includin a jaw projecting from its front edge an a. sup orting extension therefrom having a hol er. edge, a carrier of U-shape open at its. front edge to receive said extension and to slide thereon, a movable memben pivotally mounted between the side parts of said carrier at the front edge tially parallel with the other handle in the grasping position of the jaws, and a detent upon said movable member adapted to en gage said holder edge.

2. A wrench comprising a fixed jaw member including a jaw projecting from its front edge and a supporting extension therefrom having a holder edge, a movable member comprising a handle'and a jaw rigidly secured thereto, said jaw members with the handle extensions being formed of'substantinlly the same thickness, a carrier formed of comparatively thin metal wrapped about the extension from the fixed jaw member and open at one edge to receive and plvotally support said movable member, and a detent upon the movable member adapted to engage said holder edge.

3. A wrench comprising a'fixed jaw memher with. a supporting extension therefrom having a holder edge, a' carrier formed to U-shupe from sheet metal with snbstnntially parallel branches, saidearrier being slidably mounted upon said extension with the bend thereof at the back of said extension, said extension being received within the open edge of said carrier, a movable member pivotally mounted within thoopen edgeof said carrier and comprisinf a aw and a handle extending substantia 1y pnmllelwith said supporting extension when the jaws are in their grasping osition, and a detent proo rate piece of metal and rigidly secured to,

said movable member to engage said holder dg 5. A wrench comprising a. fixed jaw member' including a jaw projecting from its fronted'ge and a so porting extension there,

from having a hol er edge a carrier of U- shape closed at its back edge and open at its front edge to receive sai extension and to slide thereon, and a. movable member rewaived. within the open edge of said U- shuped jaw carrier and pivotally mounted between its side parts, said movable member including a handle and a detent to engage the edge of said supporting extension.
